WARP-BEAM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 368,122, dated August 9, 1887.

Application filed March 1, 1887. Serial No. 229,310.

To all whom, it may concern:

Be it known that I, HoRAoE WYMAN, of WVorcester, county of Worcester, and State of Massachusetts, have invented an Improvement 5 in Warp-Beams for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention in warp-beams has for its ob- I ject to provide'a simple means whereby one or both of the heads or flanges may be readily adjusted to the width of the warp to be woven into cloth.

Myinvention consists, essentially, in the com- 1 bination, with the barrel or body, of a warpbeam provided with a series of teeth or with a longitudinal rack, with a head or flange pro vided with a pinion the teeth of which engage the teeth of the rack, as will be described.

I have provided the pinion referred towith a locking device, to prevent its rotation when it is desired that the flange or head remain in fixed position.

Figure 1 shows one of my improved warp- 2 beams partially broken out, with one flange or head, its gears, and the rack, in section; and Fig. 2 is a section of Fig. 1 in the dotted line :20, the flange or head being broken out and one of the pinions being shown in section.

The barrel or body A (herein shown) has metal journals a, and, as herein shown, the barrel has at each end a toothed gear, a, all of which may be of usual construction. The barrel is grooved longitudinally at each side, as 3 5 at a and in the said grooves are placed and secured suitable toothed racks or bars, I), which are engaged by toothed pinions I), supported both in like manner by and free to turn on screw or other Studs, as d, entering one of the 40 radial ribs of the flange or head.

(No'mode-l.)

Each flange or head, as herein shown, is composed of two semicircular segments (see Fig. 2) bolted together by bolts, as 6, extended through slots in the ribs of the flanges, as best shown at the upper part of Fig.2, the said bolts, when 4 5 pushed down in the said slots to enter spaces between the teeth of the pinions, serving to lock the pinions in place, so that they cannot rotate, and in such condition the heads or flanges become fixed to the barrel.

In case it is desired to move the head or flange, as at the right of Fig. 1, the boltse are loosened and moved in the slots of the ribs, so

as to be out of contact with the pinions, as at the underside of Fig. 1, and at such times the pinions are free to turn, and consequently the head may be moved longitudinally on the barrel, the pinion in engagement with the rackteeth b rotating freely.

I claim- 1. A warp-beam having a barrel provided with rack-teeth arranged therein in the direction of'the length of the barrel, combined with a flange or head having a pinion to engage the said rack-teeth, substantially as described.

2. A warp-beam having a barrel provided with rack-teeth arranged therein in the direction of the length of the barrel, combined with a flange or head having a pinion to engage the said rack-teeth, and with a locking device for 70 the said pinion, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HORACE WVYMAN.
